ADJUSTABLE HANGER FOR OVERHEAD TRACKS.

Application filed February 21, 1927. Serial No. 170,031.

The object of my invention is to provide a novel adjustable hanger for overhead tracks such as is used for litter carriers, etc; and especially to provide a hanger of 6 novel construction which permits of quiclr and easy adjustment of the hanger to a level position, even although the timber from which it is suspended is irregular or warped. I attain these and other objects of my in vention by the device illustrated in the accompanying drawings in which Figure 1 is a. side elevation of my invention;

Fig. 2 is a vertical section on line 22 of Fig. 1;

Fig. 3 is a horizontal section on line 3-3 of Fig. 2; and

Fig. 4 is a side elevation of the hanger applied to a warped or irregular shaped timher.

Like numerals designate like parts in each of the several views.

Referring to the accompanying drawings I provide lock screws 1 having a squared portion 2 for engagement by a wrench and having a threaded end t provided with wood screw threads 8 for screwing into a timber 11. Mounted on the main threaded portion of the screw 1 are lock nuts 5 and 7 and lock washers 6 and 8 between which are mounted the opposite overhead track members 9 which are fastened together by bolts 10. 7

As shown in Fig. 4 the arrangement of the lock nuts and lock washers on the main threaded portion of the screw 1 permits of convenient adjustment for supporting the overhead track member 9 in a level position even though the timber or supporting element 11 to which the wood screw ends 3 are attached is warped, bent or irregular in shape. This feature of ready adjustability is an important improvement over similar devices in the prior art which have required a diiiicult disassembling of parts when it is necessary to adjust the hangers where the overhead timber 11 was warped or irregular in shape.

In setting up this track the screw hanger in the timber at the extreme end of the track is first screwed in place and then the hanger in the timber in the other end oi the track is screwed into place. The track is put up and levelled by the adjustment of the two hangers. After leveling the track with the two hangers intermediate hangers are put in place as follows: The lock nut is screwed to the extreme end of the hanger toward lag end, the nut is taken off the bottom of the hanger and the hanger dropped in place at the desired point and the screw fastened in the timber. The device is then adjusted to fit the track by use of the lock washer and lock nut on the bottom of the hanger. The next piece of the track is fastened in place in a similar manner until the entire track is up, the operative then going back over the track and making the necessary adjustments to bring the track into the desired alignment. .Vith this device a hanger may readily be replaced should the lag or wood screw end become loose or a timber break. The device may be installed in much less time than is required with hangers of prior types.

V] hat I claim is An adjustable hanger for overhead tracirs comprising a plurality of screws, each screw having one of its ends suitably threaded for screwing into timbers, and having the main body threaded for screwing on metal parts, and having an intervening squared portion for engagement by a wrench, a plurality of lock nuts threaded on the main body of the screw, lock washers adjacent said nuts the lock nuts and lock washers being suitably spaced to adjustably receive and engage overhead track members, whereby to facilitate bringing the track members into proper alignment even though the overhead timber from which the hanger is suspended is warped.
